Last year’s post-Lollapalooza restoration cost $200,000, paid for entirely by C3 Presents LLC, the festival’s promoter, as part of its contract with the city. This year’s anticipated cost has not been disclosed — although the damage is far worse than last year’s.

In fact, the record crowds and heavy downpours during Lollapalooza led to the “worst amount of damage” in the festival’s 20-year history, said Adam Schwerner, director for the park district’s department of natural resources. Up to 80 percent of the park was affected, which means restoration will take longer than previous years, he said.

It appears that C3, the company behind Lollapalooza, is hard at work to ensure the park gets back to its normal luster. The Sun-times has a telling picture (link here) that has a sign saying, "Please excuse the mess while we improve this park, paid for by Lollapalooza".

Please lets not make Grant Park out to be more than what it is: a large green space adjacent to the lake. Come out to Grant Park any day during the week. Locals and tourists do not visit Grant Park without the purpose of an event. Nobody comes to Chicago and says "oooh, I can't wait to see Grant Park!!" No, instead the want to go to milenium park and museum campus. Grant Park is intended for events, such as concerts, races, and general get togethers. These events stimulate the local economy. Lolla has an economic impact of 110M and the marathon brings in an addition 150M to our great city. We should embrace these events. Please remember the beauty of grass....it grows back!!

In big picture most will agree with your sentiment. However, a few concerns lingering for me is,

A. It seems since the Obama 'beginning of free stuff' election night speech, It has been non-stop crappy condition for many parts of Grant Park. Event after event something is out of service for weeks to months. The baseball field for example have been resurfaced 4-5 times.

B. Mark my words - Chicago will bungle this whole thing (just like the Fireman's exam Lawsuit) to where someone will be given $50MM because Lollapalooza is not being charged. and some other event pays, and the vultures will claim foul, racism, etc. for a quick payout.

Residents have no say in where the Lolla money is directed, yet guys like Bob O'neal will drive projects such has South grant park expansion to be paid with Tax payer or TIF Funds from those same residents.they More realistic costs borne - There should be a bit more

The Obama remark is kind of bizarre. The park has always been used by community/nonprofit groups, and I have no problem with that. That's what parks are for. Lolla is a rare -- if not the only example -- of a for-profit company using it on such a large scale, and as I've said before, this is a bad precedent.

Parks shouldn't be rented out to for-profit companies, and it's even worse when they're not paying the full cost of putting that much of the park out of commission for weeks if not months. I believe that's called corporate welfare. Sure they're restoring the damage, and supposedly doing some upgrades. But our parks should not be for sale to the highest corporate bidder.

As for Grant Park only being for "events" ... that is just not true. I go for walks there often, and am not the only one, as there are many other early morning walkers out. It gives those of us living or visiting downtown a chance to enjoy some open, green space and natural beauty. Grant Park is a gem, with some beautiful gardens. Maybe you don't enjoy it, but thousands of others do.
